Abstract
As heterogeneous wireless networks are deployed and users need more flexible mobility services, there has been a lot of research work about interworking mechanism between widely deployed 3G network and rapidly boarded WLAN (wireless local area network). On the other side, TD-SCDMA (time division-synchronous code division multiple access), which combines all the advantage of the TDD (time-division deplex) with CDMA (code-division multiple access), is one of the three main standards of third-generation mobile radio system, and is newly commer-cialized in China. It is expected to provide enough mobility and higher data rate. So the study of the integration between WLAN and TD-SCDMA will be attractive. In this paper, we propose an efficient joint session admission control scheme that maximize overall network revenue with Qos (quality of service) constraints over both the WLAN and the TD-SCDMA cellular networks. Simulation results illustrate that the overall network revenue earned in the proposed scheme is significant larger than that when the individual networks are optimized independently.
